It's widely assumed that in space combat, heavy lasers, ion cannons, and concussion missiles will be mostly useful against fighters and freighters. And that turbolasers, ion batteries, and proton torpedoes will mostly be useful against capital ships.
Now, what about on vehicles? Which weapons will be best against infantry and which against ships and other vehicles?
I'm assuming that light, medium, and heavy blasters are good for infantry, and that concussion missile launchers, medium lasers, and heavy lasers are good for vehicles and ships. Is this a probable outcome?
I think you summed it up best with "it's widely assumed" about space combat. Because as it stands right now nothing is effective against anything, and your question is merely asking others to speculate about what they thinkmight happen.
No one can answer your question because there is no answer.
I believe Tuural was referring to my space combat plan, which involves fleeing when my PLY-3000's eight sensors detect a threat (and is the one talked about in the combat threads in the general talk section). My land combat plan is totally different, and hasn't been mentioned in any forum thread except this one.
